Libby and others (University of Chicago) devised a method of estimating the age of organic material based on the decay rate of carbon-14.is the quantity of radioactive material at time zero, X is the amount remaining after time t, and k is the first order rate constant, which is a characteristic of the isotope undergoing decay.by Helen Fryman Question: What about radiocarbon dating? Response: I asked several people who know about this field. (1.) C14 dating is very accurate for wood used up to about 4,000 years ago.

The lecturer talked at length about how inaccurate C14 Dating is (as 'corrected' by dendrochronology).

The methodology is quite accurate, but dendrochronology supposedly shows that the C14 dates go off because of changes in the equilibrium over time, and that the older the dates the larger the error.

Radiocarbon dating—also known as carbon-14 dating—is a technique used by archaeologists and historians to determine the age of organic material.

It can theoretically be used to date anything that was alive any time during the last 60,000 years or so, including charcoal from ancient fires, wood used in construction or tools, cloth, bones, seeds, and leather.

Carbon has an atomic number of 6, an atomic weight of 12.011, and has three isotopes: carbon-12, carbon-13, and carbon-14.

(The numbers 12, 13 and 14 refer to the total number of protons plus neutrons in the atom's nucleus.Libby, the discoverer of the C14 dating method, was very disappointed with this problem.He understood that archaeological artifacts were readily available.If you have any more questions about it don't hesitate to write.(2.) I just listened to a series of lectures on archaeology put out by John Hopkins Univ.Despite this she continually uses the c14 dates to create 'absolute' chronologies.
